MANUFACTURE OF INLAID WORK FOR DECORATIVE PURPOSES. I

SPECIFICATION forming part of Letters Patent No. 488,542, dated December27, 1892.

Application filed Dotober 8, 1891. Renewed May 24, 1892. Serial No.434,175. (No specimens.)

T0 at whom, it 11mg concern:

Be it known that I, HENRY A. COUSINS, a subject of the Queen of GreatBritain, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in theManufacture of Inlaid Work for Decorative Purposes, of which thefollowing is a specification.

My invention relates to inlaid work for decorative surfaces wherein theoutlines and backing are of metal, and is applicable to wainscotings,pilasters, church altars, furniture, panels, slabs, and a great varietyof articles impossible and not necessary to here en umerate.

The chief object of this invention is to firmly attach the decoratedsurfaces to the metallic backing without the use of solder or otheradhesive cements for that purpose; subordinate objects are theproduction of articles in this particular branch of decoration whichshall be cheap and easy to make, equal in point of finish to any made bythe more tedious and expensive methods, and in which the backing andfront are inseparably secured the one to the other. To accomplish theseobjects and to secure other and further ad vantages in the manufactureand product, my invention includes a new and useful method and a new anduseful article, all as will hereinafter more fully appear.

Referring to the accompanying drawings which form a part of thisspecification, Figure 1, is aplau View of a fragment of the metalbacking of any article to be produced, portion of a figure beingoutlined thereon, and cuttings or perforations made therethrough inaccordance with my invention; Fig. 2, a View in cross-section showingthe backing made ready to receive the filling, that is, having metaloutline strips located thereon, and having the margins of theperforations bent up, and Fig. 3, a cross-section of a fragment of anyslab or other article finished after the manner of myinvention.

In all the figures, like letters are employed to designate correspondingparts.

A indicates the backing of sheet metal, usually copper, zinc or othersuitable metallic substance. Upon this backing I first draw or producethe desired design in outline, represented by the lines a 0.. Around andbetween the lines a a, I make, with a suitable tool, cuts through thebacking, the margins of which are indicated at b b. The points of thesecross-cuts are next turned up so as to project about three sixteenths ofan inch or thereabout above. the upper face of the backiugA by pressingthem up from the opposite face thereof; or the design having beenoutlined upon the plate as explained, the plate may be perforatedthroughout and such of the out parts as touch the outlines afterwardfiattened down or restored to their original position. The backing beingthen ready, I take rolled brass, copper, aluminium or other suitablemetal or alloy in bands or strips of about one fourth of an inch inwidth and of the desired thickness, which I bend to conform to theoutlines upon the back plate, and theseI temporarily fix in positionwith a solution of shellac and alcohol or other equivalent solution orcompound. When all the strips are propertyadj usted, I pack theinterstices with a filling, B, in the nature of apermanent cement whichis usually colored by various oxides. The filling which I prefer forthis purpose is composed of peroxide of manganese, one part, asbestus orpulverized marble, one and one half parts, and oxide of zinc, one part,the whole being mixed to a stiff paste with silicate of potash, butother compositions may be employed in lieu thereof if desired. When allthe spaces between the metal outline strips are filled, and before thefilling is hardened, I subject the plate with its applied materials topowerful pressure by rolls or in a suitable press, and when the fillingis finally hardened I polish the whole face after the usual manher ofpolishing marble. The applied pressure forces the points of the marginsof the perforations into the filling in such a manner as to securelylock the backing to the front, and at the same time forces the fillinginto all the interstices and adds to the density of the surface to bepolished, whereby perfect work and finer effects may be produced.

The method employed is simple, cheap, and convenient, the articleproduced is durable and of easy manufacture, and the invention will befound to answer all the purposes and objects herein indicated.

Having now fully described my invention,
